Effect of Soil Classification on Seismic Behavior of SMFs considering Soil-Structure Interaction and Near-Field Earthquakes

Table 1

Soil classification in Iranian national building codes [33].

Soil types	Vs	Ts (fundamental period)
Type I	750 ≤ Vs	0.4
Type II	375 ≤ Vs ≤ 750	0.5
Type III	175 ≤ Vs ≤ 375	0.7
Type IV	Vs ≤ 175	1.0
